REOEPTACLE-SEALING MACHINE.

Application filed May 29, 1922. Serial No. 564,554.

To ail whom it wmy concern.

Be it known that we, EDWIN J CONLEY, a citizen of the United States, and a resident of New York, county and State of New York, and EDWARD J. lVHALnN, a citizen of the United States, a resident of Howard Beach. in the county of Queens and State of New York, have invented a certain newv and useful Receptacle-Sealing Machine, of which the following is a. specification.

This invention relates to a receptacle sealing machine, and more particularly to a machine for fusing tin foil to the sides of a tin receptacle.

The general principles of sealing tin foil to a'corresponding metallic material have been disclosed in the patent to Edwin J. Conley, 1,398,840, andrthisinvention is par ticularly concerned with a machine for accomplishing a similar object, on packages of various characters, by the use of sealing irons enclosed in rollers between which the package is made to pass. \Vhile the invention may exist in various embodiments, for the sake of a specific description the following embodiment will be described in connection with the accompanying drawings which foun partof the specification.

In said drawings,

Fig. 1 representsa side view of the machine with the rollers separated;

Fig. 2 represents a section of the machine and rollers at right angles to Fig. 1 through the axes of therollers;

Fig. 3 represents a detailed View of modified form of roller, and

. Fig. l represents certain electrical connections which may be made for properly operating a rheostat used in conjunction with the machine.

In said drawings there are shown standards 1 and 2, each provided with grooves such as 3 and a to accommodate upper and .lower blocks 5, 6 and 7, respectively (the block for roller 12 not being visible in Fig. 2 because of the gears). Within these slidable blocks are positioned rollers 9, 10, 11, and 12, respectively, and these rollers are mounted to rotate on roller bearings as clearl illustrated in the drawings, said roller bearings being denoted generally by the numeral 13. The roller bearings are provided with suitable channels or grooves 14. cut therein for lubrication purposes, and they are set within corresponding sockets 15 in the rollers. The bearings travel within stationary annular members or races 16 which are cut away as shown in Fig. 1 so that the rollers may be brought into contact if desired. The roller bearings are supported within their sockets by the side walls thereof as shown in Fig. 1, and can only be removed by longitudinal sliding displacement. Inside of the rollers are mounted electrical heating irons such as irons 17, 18, and 19, and these may be spaced from the rollers about 1/64. a rheostat 20 by suitable electric wires as shown, the specific manner of arranging the electrical connections being described later.

At the side of the standards are provided suitable slots such as 21 and 22 adapted to receive locking bolts 23 for the purpose of engaging and holding plates such as 24, in which are mounted gears such as25 and 26 meshing with gears such as 27 and 28, the latter being keyed to their respective rollers. Driving gears 29 and 30, keyed to the shaft 31, serve to drive the various gears above described, and the shaft 31 is driven from tight and loose pulleys and 33. hen it is desired to bring the rollers 9, 10 and 11, 12 close together, the drive may be directly be tween the gears 27 and 28 without the assistance of the intermediate gears 25 and 26, in which case the plate 24 would have to be moved to the left as viewed in Fig. 1 in order to remove its gears from contact.

An adjusting screw 34; is rotatably mounted as at 35 to the top plate 5 for the purpose of positioningit in any desired position and a similar device will of course be employed on the other side of the machine.

The faces of the rollers as shown in Fig. 2 are straight, but they may have any other desired shape corresponding to the shape of the packages, as illustrated'for example in Fig. 3, where the numerals 9, 10*, 11212 and 36 denote corresponding parts. A flatsided box B is shown passing between the rollers which are shaped to fit the cover C and ridges R and S on this box.

The electrical connections to the rheost-at are shown in Fig. 4, and the purpose is to connect all of the heating irons to a single rheostat 20. The heating irons 17, 18, 19, and 20 are shown as coils in Fig. 4, and the rheostat is designated by numeral 20. Irons 9 and 10 receive current through-a wire and irons 11 and 12 through a vire 36 from the rheostat, the connection being through a single circuit 37. The currents leave through connections, 38 and 39 respectively. The electric cables 10 and 41 as shown in Fig. 1 may be provided with removable sockets so as to facilitate an instant disconnection.

In the operation of the machine, packages are suitably supplied by hand or by a feeding mechanism and fed in between the rollers so that each set of rollers will bear upon opposite sides of the package. For example, if a rectangular tin box is being fed through, it will occupy a central position and rest on opposite sides of rollers 9, 10, 11, and 12 so that the tin foil with which the tin box is covered will be fused to the top and bottom thereof along both sides throughout the entire length of the box as it passes between the rollers. Other kinds of packages may be likewise treated even though they comprise yieldable contents.

The separate sets of rollers make it possible to secure independent adjustments against the opposite sides of the packages so as to insure a secure and close contact with the rollers. The latter are heated to the proper fusing temperature by the stationary heat ing irons within them, and this heating temperature may be above 400 to 600 F. as described in the aforesaid patent to E. J. Conley. As furthermore described in said patent, the foil may be relatively thin foil, that is, foil having a. thickness less than 3/1000 of an inch, such as 1/1000 of an inch. The rheostat is of such a design that close regulation of the temperature is made possible and a reduction in the current may be easily and quickly made when the machine for any reason is running slow.y or has been stopped.

A dry lubricant such as mica may be used in the roller bearings so that none of the lubricant will work its way out onto the rollers-and interfere with the fusing operations.

As many apparently widely different e1n bodiments of this invention may be made without departing from the spirit thereof, it is to be understood that we do not intend to limit ourselves to the specific embodiment thereof except as indicated in the appended claims.

We claim:

1. A. receptacle sealing machine which comprises a linearly separated pair of rollers provided with heating means; sliding blocks carrying said rollers, each'block having an independent adjusting means for pcsitioning the rollers; and a second pair of linearly separated rollers lying in substantially the same plane as the first pair and opposite thereto.

2. The invention in claim 1 wherein the rollers have internal stationary electrical heaters.

3. The invention in claim 1 wherein the second pair of rollers is provided with positive driving means.

4t. The invention in claim 1 wherein the second pair of rollers is provided with drivprovided with means for driving them at the same rate from the driving means for the second pair.

5. The invention in claim 1 wherein the rollers are shaped to fit accurately the en tire contour of the receptacle to be sealed.

6. A receptacle sealing machine comprising two independent sets of rollers, stationary heating devices in the rollers, means for adjusting each set, gears mounted to rotate with the rollers, an adjustable intermediate set of gears mounted to be placed in mesh with the above mentioned gears, and a driving gear on a driving shaft for driving the gears.

7. A. receptacle sealing machine comprising two separate sets-of rollers each set hav ing identical axes, stationary heating devices in the rollers, independent adjusting mechanism for each set, gear-s mounted on the rollers, a movable plate provided with gears to mesh with the said gears, and driving gear on a driving-shaft to drive all of said gears.

8. A receptacle sealing machine comprising a plurality of individual rollers divided into sets lying on either side of a median plane through the receptacle being sealed, and means for heating the rollers.

9. A receptacle sealing machine compris ing a plurality of individual rollers divided into sets lyin on either side of a median plane througi the receptacle, means for heating the rollers, gears mounted to rotate with the rollers, and means for driving the gears.

In testimony that we claim the foregoing, we have hereunto set our hands, this 23rd day of May, 1922.
